MDCCCLX Roman Numerals

Professor Greenline Explaining Math Concepts

To meet their daily commerce and administration needs, the ancient Romans developed Roman Numerals. It used a combination of seven symbols — I, V, X, L, C, D, and M to represent numbers. Roman numerals were used to record transactions, keep track of data, and label military units. In this topic, we are going to learn about the Roman numeral MDCCCLX.

What is MDCCCLX in Roman Numerals?

Ancient Romans discovered that counting fingers could get very complicated after 10. So to overcome the complexity, the Roman numeric system was developed. This was widely used throughout Europe as a standard writing system until the late Middle Ages. Seven symbols are used to represent numbers in the Roman numeric system — I, V, X, L, C, D, and M.

 

The numerals are made up of different combinations of these symbols. MDCCCLX in Roman numerals can be written in number form by adding the values of each Roman numeral, i.e., MDCCCLX = 1860.

 

Let us learn more about the Roman numeral MDCCCLX, how we write them, the mistakes we usually make, and ways to avoid these mistakes.mdccclx roman numerals

Basic Rules for MDCCCLX in Roman Numerals

When writing Roman numerals, there are a few rules that we need to follow based on the Roman numerals we are trying to write. In this section, we will learn about the rules when writing Roman numerals and how to represent them.

 

Rule 1: Addition Method:

 

When a larger symbol is followed by a smaller symbol, we add the numerals to each other. For example, in VIII, we have 5+3=8.

 

Rule 2: Repetition Method:

 

A symbol that is repeated three times in continuation increases the value of the numeral. For example, XXX = 30.

 

Rule 3: Subtraction Method:

 

We use the subtraction method when a larger symbol follows a smaller symbol. For example, XL = 40 (which is 50–10).

 

Rule 4: Limitation Rule:

 

Symbols cannot be repeated more than three times, and some symbols, such as V, L, and D cannot be repeated more than once. For example, 10 is represented as X and not VV.

How to Write MDCCCLX in Roman Numerals?

Let us learn about how to write MDCCCLX in Roman numerals. There are two methods that we can use to write Roman numerals:

 

  • By Expansion Method
  • By Grouping Method
Professor Greenline from BrightChamps

MDCCCLX in Roman Numeral by Expansion Method

The breaking down of Roman numerals into parts and then converting them into numerals is what we call the expansion method. The expansion method is the breaking down of Roman numerals into numerical form and adding them to get the final number.

 

Step 1: Break the Roman numerals into parts.

 

Step 2: Now write each of the Roman numerals with its numerical digit in the place value.

 

Step 3: Add the numerals together.

 

For MDCCCLX,

 

Step 1: First, we break the Roman numerals. MDCCCLX = M + D + C + C + C + L + X

 

Step 2: Write the Roman Numerals for each part

The Roman Numeral M is 1000

The Roman Numeral D is 500

The Roman Numeral C is 100

The Roman Numeral L is 50

The Roman Numeral X is 10

 

Step 3: Combine all the numbers M + D + C + C + C + L + X = 1000 + 500 + 100 + 100 + 100 + 50 + 10 = 1860. Therefore, the Roman Numeral MDCCCLX is 1860.

Professor Greenline from BrightChamps

MDCCCLX in Roman Numeral by Grouping Method

Using subtraction and addition rules, we will apply the grouping method. This means we break the Roman numerals into smaller groups, which makes it easier to work with. This method groups the Roman numerals logically, and then we write the numbers for each group.

 

Step 1: Take the largest number and write the number for that Roman numeral.

 

Step 2: Write the Roman numeral using the subtraction and addition rules.

 

Example: Let’s take the Roman numeral MDCCCLX.

 

Step 1: The larger Roman numerals are what we will begin with.

Once split, the Roman numerals we get are M, DCCC, and LX.

The numeral for M is 1000. The numeral for DCCC is 800.

 

Step 2: Now we need to either add or subtract the smaller number, depending on its place.

Here we add LX to DCCC and we will get MDCCCLX.

The Roman numeral LX is 60.

Therefore, the numeral of MDCCCLX is 1860.

Common Mistakes and How to Avoid Them in MDCCCLX Roman Numerals

Students can make mistakes when studying Roman numerals. Here are a few common mistakes students make, and ways to avoid them.

Mistake 1

Mistakes when applying the repetition method

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

It can be quite confusing for beginners to remember that Roman Numerals cannot be repeated more than three times. Another thing to keep in mind is that Roman Numerals such as V, L, and D cannot be repeated.

 

For example, writing LL as 100 is incorrect; the correct answer is C.

MDCCCLX Roman Numerals Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

If a Roman merchant has MDCCCLX gold coins and gives away CCXLV coins, how many coins does he have left? Write the answer in Roman numerals.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The merchant has MDCCXV coins left.

Explanation

Convert both Roman numerals into their decimal form:

MDCCCLX = 1860

CCXLV = 245

Subtract the number of coins given away: 1860 - 245 = 1615

Convert 1615 into Roman numerals: 1615 = 1000 (M) + 600 (DC) + 10 (X) + 5 (V) = MDCXV

Problem 2

A historian is studying two ancient Roman artifacts dated MDCCCLX and MDC respectively. What is the sum of these years in Roman numerals?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The sum is MMDCXX.

Explanation

Convert the Roman numerals into their decimal form:

MDCCCLX = 1860

MDC = 1600

Add the years: 1860 + 1600 = 3460

Convert 3460 into Roman numerals: 3460 = 3000 (MMM) + 400 (CD) + 60 (LX) = MMMCDLX

Problem 3

A Roman architect plans to build a structure that is MDCCCLX feet tall, but decides to reduce its height by half. How tall will the structure be in Roman numerals?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The structure will be CMXXX feet tall.

Explanation

Convert MDCCCLX into its decimal form:

MDCCCLX = 1860

Divide by 2: 1860 / 2 = 930

Convert 930 into Roman numerals: 930 = 900 (CM) + 30 (XXX) = CMXXX

Problem 4

During a festival, a Roman citizen distributes MDCCCLX loaves of bread equally among XV families. How many loaves does each family receive? Write the answer in Roman numerals.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Each family receives CXXIV loaves.

Explanation

Convert the Roman numerals into their decimal form:

MDCCCLX = 1860

XV = 15

Divide the loaves by the number of families: 1860 / 15 = 124

Convert 124 into Roman numerals: 124 = 100 (C) + 20 (XX) + 4 (IV) = CXXIV

Problem 5

Convert MDCCCLX into its decimal form.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

In decimal form, MDCCCLX is 1860.

Explanation

Break down MDCCCLX into components:

M = 1000

D = 500

CC = 200 (C + C)

L = 50

X = 10

Add the values: 1000 + 500 + 200 + 50 + 10 = 1860
